## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability afriref-certified-pan-african-government-reference-data-5cbb42fb
```

Example prompt: What is the current VAT rate in Kenya? I need a certified, cryptographically signed answer with the archived source and SHA256 hash so I can use it in a compliance report.

## When to prefer this

Choose this endpoint when you need not just a reference value but a cryptographically verifiable, citable extract — e.g. for compliance reporting, audit trails, legal documentation, or any context where the provenance and authenticity of African government reference data must be proven. Prefer it over raw or uncertified data sources when downstream consumers (auditors, regulators, counterparties) require a signed, archived record. The Ed25519 signature and SHA256 archival hash make it uniquely suited to trust-sensitive workflows.

## Known failure modes

- Unsupported country code returns an error (only 34 African countries supported)
- Unsupported series identifier returns an error (only 12 series supported)
- Unpaid or uncharged request is refused without evidence of payment (x402 payment required)
- Stale or unavailable upstream government source may delay or prevent a fresh certified extract
- Invalid or missing path parameters result in a 400/422 error

## How this service works

Kenya: VAT standard rate — gazette-cited JSON with last_confirmed and stale.

## Output

A JSON object containing the reference value for the requested series and country, accompanied by a citation (source name and URL), an archived-source SHA256 hash, an Ed25519 digital signature, and a verification chain — together constituting a cryptographically certified extract of official government data.
